How to download music for free without P2P software
If you want to download songs of your favorite bands, but don’t understand how all peer-to-peer software works or you are worried about facing legal consequences by downloading from P2P networks, then you might want to use a program called Clickster.
Clickster uses Google and other search engines
Clickster is a freeware program and is really easy to use. Once you have it installed, it loads up with a simple interface where you type in the name of the song or artist and the search begins! You can download the files directly or you can play them through the interface by double clicking on the song name.
Pretty sweet! No need to worry about downloading bloated P2P software that might have spyware if you just want to listen to a little music while working on your computer!
